"This video is proof that Google Glass will change citizen journalism forever," Barrett wrote on his YouTube page. While all citizen journalists armed with a camera or a smartphone could capture similar video, Barrett told VentureBeat that the fact the glasses were relatively unnoticeable made a big difference:

"I think if I had a bigger camera there, the kid would probably have punched me," Barrett told me. "But I was able to capture the action with Glass and I didn't have to hold up a cell phone and press record."

"In May, the [US] House Bipartisan Privacy Caucus wrote Google a letter, asking for more information about how Google Glass will work within the company's privacy standards. Last month, 10 privacy regulators from around the world, including Canada, Australia and a European Commission panel, asked Google for more information on how the company's headset complies with their data protection laws and what data it collects."
